I agree. Especially with the 'always' part: "Anyway, it is always a good programming advice to minimize the number of arguments. Zero or one argument is easiest to understand and maintain." How is one to minimize the number or arguments in a purely functional language with immutable state? How can I do tail recursion without any arguments?
